eration being accomplished by reason of the form of the groove 8 in the stationary jaw 7 and the slot 10, through which the pin 11 passes, is Wider than the diameter' of said pin in order to facilitate this operation of the bar 9.

In Fig. 4 I have shown an ordinary brace or stock 20, which is provided withY the usual socket-head 21, in which is formed an angular socket 22, which is, adapted to receive the angular end 23 of the shaft or shank 5 of the Wrench, and by means of this device the Wrench may be operated in the manner of an ordinary brace-bit.

I have also shown in Fig. 5 a supplemental attachment consisting of a bar 24, which is provided at one end with a head'25, in which is formed an angular socket 26, similar to the socket 22 in the brace or stock 20, and this device may be connected With the shaft or shank 5 of the Wrench and with the brace or stock 20, so as to lengthen said shank or shaft, and said attachment is provided with two transverse angular openings 27 and 28, Which are adapted to receive the end 23 of said shank or shaft of the Wrench, and when thus used the attachment will constitute an ordinary handle, as will be readily understood.

My improved Wrench is simple in construction and o'peration and is perfectly adapted to accomplish the purpose for which it is intended, and it is apparent that changes in and modifications of the construction herein described may be made Without departing from the spirit of my invention or sacrificing its advantages.

l-Iaving fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A Wrench, comprising a shaft or shank vadapted to be held by a brace and which is provided With an oblong cross-head, one end of which is provided vwith a stationary jaw, said cross-head being provided with a longitudinal groove in which is mounted a sliding bar which is provided With a supplemental jaw, said bar being provided With teeth on its lower side Which are adapted to engage with corresponding teeth formed in saidv head, and also with a longitudinal groove, which is adapted to receive one end of a spring-operated lever Which is pivotally connected With said head, and adapted to hold the teeth or' said supple-mental jaw in` contact With the teeth of said slot, substantially as shown and described.

2. A wrench, comprising a shaft or shank Which is provided with an oblong cross-head. one end of which is provided with a stationary jaw, said cross-head being provided with a longitudinal groove in Which is mounted a sliding bar which is provided With a supplemental jaW, said bar being provided with teeth on its lower side Which are adapted to yengage With corresponding teeth, formed in said head, and also With a longitudinc lgroove. which is kadapted to receive one end of a spring-operated lever which is pivotally connected with said head, and said bar being also provided with a longitudinal slot through which is passed a pin, substantially as shown and described.
